To all witwait may comem:

Be it lmown that-I, CHARLES W. Srnvnar,

' a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to an improvement in hydrocarbon burners of the general character Vshown in Patents Nos. l738,635 and' 710,899, issued to me on Sept.-8, 1903' and Oct. 7 1902, respectively; and it has for its object the provision of a simplified and vefficientburnerof this class, adapted for inexpensive construction and eicient operation. The burner is constructed to operate under the general principles involved in the burners described in the patents above referred to, havin a curved air pipe which brings the air in rom the side of the burner, over it, and discharges the air downwardly upon the supply of hydrocarbon contained in the cup in the center of the burner. i This air pipe is illustrated as being provided with ytwo induction branches and one outlet; this for the reason that a pipe of such form does not interfere with the upward play of the `flame from the bowl shaped base, or body portion, ofthe burner. But this pipe may have three or four induction branches without interfering materially with the lialncl In the accompanying drawings, Figure l is a vertical sectional view of the burner. Fig. 2 is a plan View of the base, or body portion, of the saine. Fig. 3 is a bottom plan view of the air pipe.y

In the drawings 5 designates the base of the burner which is constructed with a central bowl 6 and flange 7, flange 7 serving tosu port the burner on a ring or other suitabl)r supporting member which connects it with the stove 0r furnace structure in which Vit is used. Leading up through the bowl are two air passages 8, the walls 9 ofA which are formed integrally with the bowl. These' passages are preferably triangular in shape with their apexes toward the center of the bowl so that they offer a minimum obstruc tion to the play of the flame in the bowl.

This, however, is a point of minor consideration, it being possible and practicable :tor the passages to be circular in cross section, or any other shape. The walls of the Vpassages do not extend to the level of the top of flange 7 and shoulders 10 are thereby specificaties of Leners ment.

formed near the innerifedges of thevlange. Air pipe 11` is adapted to rest with its two induction branches 12 .upon the upper ends of walls 9 and inside shoulders 10. Its outlet branch or opening 13 allows the air to flow downwardly over the center of the bowl.

Located in the bottom center of the bowl is a cup 14 which is su plied with li uid hydrocarbon by means o a pipe 15 lea ing through the bottom of the bowl. This cup .14 is raised above the bottom of the bowl and is supported by a cone 16 having a plurality of circular troughs 17 0n its sloping surface, the oil which overflows the cup beingcaught in these troughs.

The actio'n ofthe'burner is similar to that described in the above named patents. The draft formed by the burning hydrocarbon causes a movement of air as indicated by the arrows, the heated and burning o il is carried from the edges of the cup down the side of the'cone and out into the bowl by the draft, the globules of oil carried by the draft thus being supplied with sutlicient air to insure efficient burning. y

Having described my invention, l claim l. An oil burner, comprising a bowl shaped base, an oil cup in the center of the base, walls formed within the bowl of the base and inclosingau air passage leading from the under side of the base in nvarrlly through the same, and an air pipe leading from the upper end of the passage and discharging at a oint over the oil cup.

2. An oil urner, comprising a bowl shaped base, lan oil .cup formed integrally with 'the base and situated in the bottom of the base, walls formed integrally. with the base within the bowl thereof and inclosing vertical-air passages inside the bowl of the base and near the outer periphery thereof,

and an air pipe having linduction branches connecting with the vertical passages and having an outlet discharging air directly over the oil cu and into the base.

3. An oil urner,4 comprising a bowl shaped base, an oil cup formed integrally with the'base and situated in the central lower portion of the base at a small distance above the bottom, Walls formed integrally with the base within the bowl thereof and nclosing vertical air passages within the bowl of the base and near the periphery thereof, and anair pi havin induction `branches connecting with the air passages and having a central downwardly outlet opening adapted to disc downwardly over base.

5 4. An oilburner,

projecting 'arge air the oil cup and into the shapedbase, a-frusto-conical member raised in the' central lower conical member having 1n its lateral face formed in its top, to the oil cup an annular'trough having an oil cup oil lsupply means leading walls formed integrally with the base within the bowl thereof and inclosmg a ated msi e air of vertical gir passages situthe bowl of the base and near comprising a. bowl'- y downwardly `over the oil cup `and lnto the en portion of the base, the' base` In witness that I claim the foregoing 'I have hereunto subscribed my name this 20th day of Sept. 1909. l CHAS..
